The beautiful Oulu Cathedral stands in Oulu’s monumental centre, on the same site where several church buildings were located over the centuries, with the oldest dating back to the late sixteenth century. The wooden church that was built on the site in the 1610s was replaced by a cathedral designed by Daniel Hagman of Sweden and completed in 1777. The cathedral, built of natural stone, was so big that all the 2,400 inhabitants of Oulu could fit in it at the same time!
